I passionately adopt ideas of agile development and successfully completed several enterprise projects using these techniques.
Before programming in Ruby I participated in development of enterprise solutions (used Java, C++). I have major in mathematics and computer science, therefore, I can apply effective algorithms with the maximal simplicity of code.

I'm a professional web developer with a strong mathematical education. I took 24th place at All-Russian Mathematical Olympiad in 2008.
My main principals are:
✓ to keep your deadlines (to be working as much as need if need)
✓ to keep code clear
✓ to keep application stable
I was working with enough clients. One of them was a Russian bank(I have developed a security inner system for them). Also I was working with market force international group.
I know how to have a professional approach to what I'm doing. And my live projects are evidence that I'm pro and my clients are satisfied.
So I'm looking forward new interesting suggestions.

Ruby has been my main language for a number of years now. I also use Javascript frequently (on the client and server), and Java and Perl when the need arises. I use Ruby on Rails for a number of projects, but a large part of my Ruby work is outside of Rails, as ruby is now my primary language.
I have a great deal of SQL experience but have been using noschema databases for most new projects for a couple of years (specifically MongoDB).
I have been working in a freelance environment for a number of years, and have a multi-machine linux-based network with constantly running infrastructure suited to tackle any task as it arises. I do a reasonable amount of system administration for my own pleasure or in the cloud for clients, and also run and administer client production deployments myself.
